A network architect is designing a new core switch and wants to ensure that heavy management traffic, such as SNMP polling, does not interfere with the forwarding of user data. Which design principle should the architect apply?

Place all management protocols on the same VLAN as user data to simplify configuration.

Logically separate the management plane from the data plane so management traffic is processed independently.

Disable the control plane to free up resources for the data plane.

Use only hardware switching for management traffic.

A network administrator is troubleshooting intermittent packet loss on a router. The router is forwarding transit traffic using hardware ASICs, but some packets are being dropped. The administrator discovers that the router's CPU is pegged at 100% due to a routing protocol process. Which type of traffic is most likely to be dropped?

Transit traffic that is forwarded by hardware ASICs

Traffic that is switched based on the CAM table

Traffic that is forwarded based on the FIB in hardware

Packets that need to be punted to the control plane, such as packets with IP options

A network architect is designing a new core router and wants to ensure that a failure in the control plane does not affect the router's ability to forward traffic. Which design approach should the architect use?

Use only software switching for the data plane.

Place the control plane on the same CPU as the data plane.

Implement graceful restart and NSF (Non-Stop Forwarding) to allow the data plane to continue forwarding during control plane restart.

Disable the control plane to free resources for the data plane.

A network engineer is designing a router to support both high-speed packet forwarding and dynamic routing protocols. To ensure that the forwarding performance is not degraded by routing protocol updates, what should the engineer do?

Use software switching to allow the CPU to handle both forwarding and routing

Disable the management plane to free CPU for routing protocols

Run all routing protocols in the data plane to reduce CPU load

Use hardware-based forwarding for the data plane and dedicate CPU resources to the control plane

A network administrator is troubleshooting a routing loop in a switched network. The administrator suspects that Spanning Tree Protocol (STP) is not converging properly. The administrator checks the switch's CPU utilization and sees that it is high. Which action would best help diagnose the STP issue without affecting data-plane forwarding?

Disable STP on all interfaces to stop the loop

Enable debug spanning-tree events on the switch

Reboot the switch to clear the STP state

Check the MAC address table on the switch
